Brief Description
Aluminium Conductor Steel Reinforced (ACSR) is one of the most widely used traditional overhead conductors in power transmission and distribution. It combines the excellent electrical conductivity of stranded aluminium with the high tensile strength of a steel core, providing reliable performance under mechanical loads, environmental stress, and fault conditions.
APAR’s ACSR conductors are engineered and manufactured to meet stringent quality standards and the demanding requirements of utilities, EPCs, and global transmission & distribution networks.
Key Advantages
- High electrical conductivity for efficient power transmission
- Enhanced tensile strength due to steel core reinforcement
- Excellent performance under dynamic loads (wind and ice)
- Proven reliability across diverse climatic conditions
- Strong resistance to mechanical fatigue and sagging
- Long service life with minimal maintenance
Available Variants
APAR offers a broad range of ACSR conductor variants designed to meet various project needs, including:
ACSR Conductor with stranding from 6/1 to 150/37 with maximum Conductor diameter upto 60mm.
(Variants are defined based on aluminium cross-section, steel core configuration, mechanical ratings, and specific utility requirements. Customized designs available on request.)
Applications
- Overhead transmission & Distribution networks
- Rural and urban power systems
- Renewable energy evacuation lines
- Industrial power distribution
- Utility system reinforcement
Standards & Quality
APAR’s ACSR conductors are manufactured in compliance with relevant IS, IEC, EN, AS, GOST, ASTM CAN/CSA, ABNT, NBR & other international & utility standards, ensuring dimensional accuracy, electrical integrity, and mechanical robustness & Environmental sustainable.
Each conductor manufactured through very stringent quality standards, rigorous testing at every stages including Type Testing and validation.
Construction & Material
ACSR conductors consist of multiple layers of high-conductivity aluminium strands stranded around a central steel core. The steel core provides mechanical strength while the stranded aluminium layers ensure excellent electrical performance.
The combination of aluminium and steel makes ACSR ideal for long spans, high loads, and varying environmental conditions.
